> When trying to install the following version in an OSGi (Equinox) environment:
> [https://repo.maven.apache.org/maven2/org/apache/tika/tika-core/4.1.0/]
> It fails like this:
> {color:#ff0000} ERROR: org.eclipse.equinox.p2.director code=0 Missing
> requirement for filter properties ~= $0: Apache Tika core 4.1.0
> (org.apache.tika.core 4.1.0) requires 'osgi.serviceloader;
> (osgi.serviceloader=org.apache.tika.detect.Detector),

> I believe the OSGi metadata is ill-defined. In particular the following
